...the two shots below stood out for me. The first has a good composition using the props well to create a diagonal line across the frame centering viewer interest on the main subject. I also think the lighting on the watch is good in this shot. The 2nd image is a good example of a lume shot that also shows the watch well. I much prefer this sort of shot to one where only the lume is visible in darkness.

Watch the white balance. These shots all have a degree of blue colour cast to them. Check your user manual for info on white balancing and set it to match the type of lighting or do a custom white balance. Look critically at the colour of the subjects in the images, the metal of the watch being probably the best to judge, and compare it to what the real thing looks like. We don't necessarily always need to aim for an exact match to reality, but something that looks "natural", (apart from those time when we are trying for a special effect).
